In May 1272, Aldert was passing through White Orchard, eager to reach the front lines of the Third Northern War, in order to describe and catalogue it in what he hoped would be his magnum opus. While in the small, war-torn village, he dropped into the local inn at the same time as Geralt and Vesemir and attempted to teach some locals how to play gwent, though both parties got more frustrated than anything else.

Shortly after, in his misguided attempt to be in the middle of the action, Aldert was caught and hung from Velen's Hanged Man's Tree by an unknown faction.
